RADIATOR- FOR AUTOMOBILES AND THE LIKE.

Specification of Letters Patent.

Application filed April 21, 1920. Serial No. 375,500.

To (ZZZ whom it may concern:

Be it known that I, HARRY BIoHUNsKY, a citizen of Russia, and a resident of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Radiators for Automobiles and the like, of which the follow ing is a specification.

This invention relates to an improved radiator for automobiles and the like, which invention relates particularly to the conduits that conduct the water from the top to the bottom chambers of the radiator, the improvement consisting of water conduits which are zig-zag or corrugated to cause the water that passes through them to pursue a staggered or circuitous course, these conduits being assembled with their projections abutting so as to provide air passages or ducts between them so that the walls or the water conduits are subjected to the cooling influence of air passing through the radiator.

The invention consists of a radiator of this type which has the water conduits provided near their edges, where the projections abut, with recesses so that the assembled conduits provide openings, these openings not only stii fening the structure, but pro viding anchors for solder, so that when the assembled conduits are dipped in the solder enough solder will lodge in these holes to bind all the solder together more thoroughly and thus make the joining of these parts more secure.

The invention further consists of a sheet of metal which is formed so that when folded over and assembled each sheet pro vides the opposed walls of a water conduit; in other words, each sheet forms a wall of each of two adjacent water conduits, that is, the folded over strip provides the opposed walls of a set of aligned air ducts or passages.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a front view of the top part of several water conduits, the one to the right being shown in section. Figure 2 is partly an elevation and partly a section of the construction shownjn Figure 1, the section being taken on a plane indicated by line 22 in Figure 1, and Figure 3 is a perspective view of the edge of the strip that I prefer to use in making up my improved radiator.

I have not illustrated in the drawing the top or bottom chambers of the radiator, these forming no part of this invention, and they can be or any desired construction. I do, however, illustrate, in the top part of Figure 1, conduits formed to show where they are in communication with the top water chamber of the radiator, the sect1on shown to the right of Figure 1 illus trating how these water conduits communicate directly at the top with said water chamber.

The water conduits are made of ver Y thin sheet metal, which metal comes in long, comparatively narrow strips and can be formed by dies into the desired shape with but slight expense and in a short time. each water conduit 10 being corrugated and preferably of zig-zag form, one wall 11 of each. conduit and the other wall 12 being formed of different strips of sheet metal, each sheet metal strip being folded over to form the ad acent walls of two diflerent water conduits.

In Figure 3 I show, in perspective view and considerably enlarged, one edge of the strip or sheet which is bent over to form the series of air ducts, these incidentally forming one wall of adjacent water conduits, the strip 13 being corrugated or zigzag, as shown, and having an off-set portion linear the edge, this oft-set portion or strip being formed all to one side of the strip, so that when the strip is folded over as shown no lgures 1 and 2, the outer side of each projection 15 fits into the inner side 16 of the projection on the next adjacent strip so as to form no closures over the water conduits or passages 10.

A second ofl set strip 17 is arranged adjacent to the off-set 14 and is preferably at the very edge of the sheet of metal, the turn or projection 18 on the projection at one edge of the sheet being substantially flush with the turn or projection 19 of the main or body portion of the strip, but at the other end, as at 20, projects beyond the projection 15 of the first strip so as to fit in the recessed part 18 of the adjacent strip against which it is seated, this being accomplished by arranging the angular parts of the ofi-set strip 17 at a more acute angle than the main corrugations of the sheet or strip 14, since 13 and 14: are substantially parallel, and it will be readily seen that this arrangement of the second strip at an acute angle permits the fitting of the projecting part 20 into the part 18 to insure a tight joint being extended from the inner edge of the off-set stri 3 14 to the outer edge of the off-set strip 1, as will be clearly seen from Figure 2.

It will also be noted that these off-set strips, when the conduits are assembled, form recesses on the opposed faces of the walls of the air ducts, these recesses 21 in the opposed conduits forming openings 22, which openings are inset from the edge the width of the strip 17 and are substantially the width of the strip 14 and thus form openingsin each of which is seated a small amount of solder when the assembled conduits are dipped into solder, as is usually done in the construction of this class of goods, to cause a sealing of the front and back edges of the conduits, thus "forming a more thorough connection and seating of the film or thin body of solder that becomes the closing medium for the edges of the assembled sheets.

It will be noticed that every alternate sheet 13 is flattened out at the top, as at 23, and the sheets in between are brought to a sharp fold or bend, as at 24, so as to insure the opening of each of the conduits 10 into the upper water chamber of the radiator.

' It will be evident, in my improved device, that the radiator is made of strips, each of which is alike, the corrugations of said strips being substantially the same, except for the angular arrangement of the oif-set strip 17 which, it must be borne in mind, is substantially flush with the bend 19 0t 7 the main part of the water conduit, but

which projects at the other end, as at 20, to be seated into the recess 18 of the next adj avery thin gage of metal can be used, the formation of the edge insuring it against distortion under normal strain.

I claim:

l. A radiator comprising a series of water conducting conduits of a corrugated form,

said conduits being assembled with the projections of one abutting on the projections of the other, the projection of each conduit being recessed near its edge, said recessed parts abutting so as to form openings be tween the conduits.

2. A radiator comprising a series of'water conducting conduits of a zig-zag shape, said conduits being assembled with the projections of one abutting on the projections of the other, the spacebetween the projections forming air ducts, the walls of each conduit being pressed together a short distance from each edge and having a recessed part within said distance, whereby two of said abutting recessed points form an opening communieating between adjacent air ducts.

3. In a radiator, a sheet of corrugated metal having a strip off-set near its edge, and a second offset strip at the edge and adjacent to said first off-set, said second ofi'- set being disposed at a more acute angle than the first.

4'. In a radiator, a sheet of corrugated metal having a strip off-set near its edge, and a second off-set strip at the edge and adjacent to said first off-set, the second ,ofiset being substantially flush with the main corrugations of the sheet on the projection on one side of the sheet, and projecting beyond the first olt-set on the projections on the other side of the sheet.

In testimony that I claim the foregoing, I

cent conduit, this double off-set insuring the" have hereto set my hand, this 20th day of formation of the openings 22 for the purposes above described, and also very much stifi'emng the edges of the sheet so that a April, 1920. 1
